DEVICE FOR FEEDING NONSLIP MATERIALS TO BRAKE LININGS.

Application filed October 29, 1924. Serial No. 746,512.

To all whom it may concern:

Be it known that I, LAWRENCE J. Rosn, a citizen of the United StatesofAmerica, residing at the city of St. Louis, in the State of Missouri,have invented certain new and useful Improvements in Devices for FeedingNonslip Materials to Brake Linings, of which the following is aspecification, reference being had therein to the accompanying drawing.

My invention relates to improvements in devices for feeding non-slipmaterial to brake linings, and has for its object to provide a chamberhaving an orifice extending to the point of discharge of the non-slipmaterial, and means controlled by the operator for releasing a charge ofsaid material from the said chamber.

The class of material primarily intended to be used with the device ofmyinvention is the viscous compound now commonly used for the treatmentor dressing of automobile brake linings; but the device is adapted tooperate on non-slip material of various types and to apply such materialto brake linings of any type.

Drawings.

In the drawings, Fig. 1 is a side elevation of the push mechanismactuating the device of my invention; the same being mounted in asection of floor, conveniently to the foot of the operator.

Fig. 2 is a longitudinal vertical view of a device embodying myinvention mounted in place upon a brake band.

Fig. 3 is a front view of the mechan sm shown in Fig. 1, top and bottombeing broken away.

Fig. 4 is a transverse vertical sectional view of the device shown inFig. 2.

Fig. 5 is a plan view of the connections between the push mechanism anda pair 0 the devices, as mounted in an automobile.

Fig. 6 is a transverse sectional view taken on the line 6-6 of Fig. 2.

Description.

As shown in the drawings a cylindrical container 7 having a conoidalbottom 8 and tubular discharge nozzle 9, mounted by brackets 10-10 uponthe upper face of a brake band 11 having the brake lining 12; the nozzle9 extending through the aperture 13 in the brakeband 11 and into theaperture 14 in the brake lining 12, as shown.

Within the cylindrical container 7 I provide the valve 15, which is inthe form of a hollow tubular rod having the lower termi-- nal nipple 16extending into the interior of the nozzle 9, having the peripheralshoulder 17 whereon the perforated disk 18 is fixedly mounted and havinga constricted upper terminal 19 extending through the center ofthe'upper perforated disk20, the coiled spring 40 being seated upon theupper face of the perforated disk 18 and holding the perforated disk 20firmly in place against the lower mouth of the screw cap 22.

Through the hollow center of the tubular rod valve 15 extends the pin21, as shown in Fig. 4, said pin 21 projecting to the mouth of thenozzle 9, its purpose being to prevent the clogging of said nozzle 9.

The perforated disk 20 is held in place by the pressure of the screw cap22 (see Figs. 2 and 4), which screw cap 22 has the concentricscrew-threaded mouth 23, which mouth 23 is in turn provided with theclosure 24. The goose-neck lever 25, is mounted transversely through thecontainer 7 as shown in Fig. 4, its hump 26 being so disposed as tooperate against the bottom of the perforated disk 18, before opening thevalve 15, while its terminal crank arm 27, having the eye 28 at its freeextremity, is connected with the corresponding eye 29 by the cord 30,and is actuated by pressure exerted upon the button 31, depressing thepush rod 32 having the foot 33 bearing upon the arm 34 of the lever 35,which is fulcrumed on the pin 36, all as shown in Fig. 1. The devicethus described is usually to be mounted in pairs as shown in Fig. 5, soa single one of the push button mechanisms shown in Fig. 1 will serve tooperate the pair of devices.

It is desirable with a non-slip material of f the kinds now commonlyused for the treatment of brake linings, to be able to ascertain whenthe container 7 is fully charged with such material; and for thatpurpose I provide near the edge of the mouth of the container 7 the vent37 and within the screw cap 22 the vent 38, these vents being sodisposed that they will register with each other when the screw cap 22is almost, but not quite, closed. While the material is being charged inthe container 7' through the tubular mouth 23 of the screw cap 22 vents37 and 38 are to be kept in alinement, so that when the charge ofmaterial has risen to the level of said vents 37 and 38 it willdischarge through said vents, whereupon a short turn of the screw cap 22will carry said vents out of alinement to the relative positions shownin Fig. (5, and the closure 24 will thereupon be seated in place, thedevice being properly charged for use.

111 ode of operation.

As will be apparent from the foregoing description of the various partsof my device the discharging of non-slip material from the container 7is under the control of the driver of the motor vehicle on which mydevice is installed; the failure of the brakes to grip properly beingindicated by their failure to promptly hold when applied, a depressionof the push button 31 working through the cord 30 serves to throw thecrank 26 against the lower face of the perforated disk 18, opening thevalve 15 and permitting a charge of non-slip material to drop into thenozzle 9 and so into the orifice ll in the brake lining. This operationis usually performed while the vehicle is in motion; the non-slipmaterial passes through the orifice let to the face of the drum 40, therotation of which drum 40 serves to distribute the non-slip materialupon the face of the brake-lining 12. This operation is repeated asoften as the necessity for treating the brake lining is indicated.

Various modifications may be made from the device as illustrated anddescribed without departing from my actual invention as that inventionis defined in the following claims.

(/Zaims 1. In a device of the class described, a container mounted upona brake band; a terminal nozzle therefor extending through the brakeband to the brake lining; a valve control for said nozzle; a screw capfor said container and vents formed respectively on said container andsaid screw cap and arranged to be thrown into or out of registrationwith each other.

2. A device of the class described compris ing a pair of valvccontrolledcontainers, each mounted upon a brake band and each having a nozzleextending through the brake band whereon it is mounted to the brakelining; and a single push-button mechanism arranged to simultaneouslyoperate both of said containers.

3. In a device of the class described, a. container mounted upon a brakeband; a nozzle therefor extending through the brake band to the brakelining; a tubular rod valve having a lower terminal nipple extendinginto the interior of the said nozzle; and a pin mounted in said tubularrod valve and projecting to the mouth of said nozzle.

In testimony whereof I have hereunto affixed my signature.
